TWO-WHEELED VEHICLE,

SPECIFICATION forming part of Letters Patent No. 433,833, dated August 5, 1890.

ings, forming part of this specification, in

which Figure 1 represents a side elevation of a two-wheeled vehicle embodying my invention and showing one of the wheels removed. Fig. 2 is a cross-sectional view of the same on the line X X of Fig. 1. Fig. 3 is a detail showing the springs arranged in pairs.

My invention relates to the general class of vehicles, and especially to the class of two-' wheeled vehicles known as road-carts, and my invention consists in the constructions and combinations of devices which I shall hereinafter fully describe and claim.

In the accompanying drawings, A represents the main axle, upon the opposite ends of which the wheels 13 are mounted and adapted to rotate, and C is the body of the vehicle having a seat portion D supported thereon in any suitable manner, the said body having a railing a surrounding its rear portion. The axle or shaft A is arched at its central portion, extends across the vehicle between the seat and bottom of the body portion, and has secured to its upper surface near the central portion thereof suitable bearings, lugs, or pins 1), adapted to have fitted to them one end of the springs E, whose opposite ends are free and are connected to an eye 0 or similar device on the floor of the body by means of a chain of loose links or other flexible connection, as shown at d. These springs are of peculiar construction and arrangement. They are arranged in pairstwo pairs being preferably upon each side of the axle-and each spring consists of a single piece of metal, heavy wire, or otherwise, one

end of which is first secured to its pins, lugs, or bearing 1) and carried downward toward the sides of the body, where it is then coiled, as at e, and its free end extended inward in an approximately horizontal plane, crossing the other or inclined arm of the spring, and has its free end secured to a pin g or like device.

WVhile' I prefer the springs being arranged in pairs, it is not absolutely necessary that such should be the case, as single springs may be used; but in either instance the springs on the right side of the center of the axle are reversely arranged to those on the left side. In other Words, the springs on the same side of the axle, (front or rear,) after being secured to their respective pins or lugs, extend in opposite directions toward the sides of the body,

and are coiled and secured at their free ends in the manner previously mentioned. After being thus arranged the pins or connections which unite the free ends of all the springs upon the right of the center of the axle and the pins or connections which join all the springs on the left of the center of the axle are connected with the eye, loop, or projection 0 in or on the floor of the body of the vehicle by any flexible connection d, such as .a chain or series of links. From this description it will be seen that the weight of the body of the vehicle and of the occupant is transmitted through the flexible connection 61 to the free ends of the springs, which ends are pulled down against the resistance of the coils. This construction permits a free vertical movement, but prevents the disagreeable lateral or side motion, due to the movement of the horse, from being communicated to the body and seat of the vehicle.

Suitable spring-plates F and F, having their inner ends clipped to the axle, extend forward, one above and bne below each shaft or thill G, and have their forward ends joined by rods h, which pass through holes h in the shafts, while the front end of the lower plate F is connected to a cross-bar Z on the front of the body A by means of a link or loose connection m, whereby the front of the body is joined directly to the springplates F. Around the rods it, above and below the shafts or thills, are coiled springs a, which serve as cushions and as a means for holding the front of the body in its proper position and also allowing for the up-and-down or vibrating movement of said front.

The inner ends of the shafts or thills are pivotally held between lugs r on the forward ends of plates .9, which lie between the inner ends of the spring-plates and the bottom of the axle, and are held in place by the clips before mentioned as securing the plates F and F to the axle.

To provide as much comfort as possible for the occupant of the vehicle I construct the seat with a lazy-back H, which is secured to standards t, that are coiled at If just under the back of the seat, and have their opposite or lower ends secured to the under surface of the seat in any suitable manner.

A vehicle constructed as above described overcomes the horse motion of the common road-cart. It permits the cart to ride easier over rouglrroads or obstructions, as the box or body of the vehicle is permitted to yield, so that when the wheels are passing over an obstruction or irregularity in the road the box or body remains level, thereby saving the driver or persons riding in the cart the disagreeable jolting common to many of thecarts now in use.

While I have described my invention as being adapted to road-carts, I do not limit it to such carts, as the same constructions may be used on four-wheeled vehicles, with or without a box, like the one shown.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a road-cart, a body portion suspended from the main axle, and a spring-connection between the body and axle having one end secured to the center of the axle and the other secured to the center of the floor of the body, substantially as herein described.

2. In a road-cart, a body portion and an arched axle extending above and across the same, in combination with oppositely-extending springs, each having one end securedto the center of the axle and the other end secured flexibly to the center of the floor of the .body, substantially as herein described.

3. In a road-cart, a body portion having a seat supported thereon, in combination with an axle having its central portion arched and extending across the vehicle between the seat and floor of the body portion, and springs secured to the central portion of the axle and having their lower ends secured to the center of the floor of the body portion by means of a flexible connection, substantially as herein described.

4. In a road-cart, the body portion and the axle extending across the same above the floor thereof, in combination with op positelyextending springs having one end secured to the axle and the opposite end free and secured to a connect-ion which is secured to the center of the floor of the body, substantially necting the free ends of the springs with the center of the floor of the body portion.

6. In a road-cart, the body portion and the axle extendingacross the floor of the same, in combination with oppositely extending springs, one end of which is secured and the other free, said springs having a portion between said ends coiled, and a chain or link connection uniting the free ends of the springs with the center of the floor of the body portion, substantially as herein described.

7. In a road-cart, the axle, the body portion, and the Shafts or thills, in combination with the springs, plates F and Fabove and below the shafts, having their inner ends clipped to the axle and their outer ends joined by rods passing through the shafts, and springs on said rods between the plates and shafts, substantially as herein described.

8. In a road-cart, the combination of the body portion having a cross-bar at its front, the axle, the spring-plates clipped thereto and joined at their outer ends, and a link-connection between the outer ends of the plates and the cross-bar, substantially as herein described.
